Unformatted text preview: OPTI 280 Assignment 13 Spring 2010 This assignment is due in one week. Each assignment is worth 100 points, and assignments that are handed in late will be penalized 15 points per week. NOTE: To receive full credit for any problem, you must hand in printouts of all programs you are asked to write as well as printouts of all command window output and any plots that the programs produce. All programs must conform to the programming rules handed out at the beginning of the semester. Write the answers to the question(s) associated with each problem at the end of program for that problem (on the same sheet, if possible). Upload your code to the D2L dropbox. 1. The Fraunhoffer diffraction pattern from an aperture is proportional to its 2D Fourier Trans- form. You will learn about diffraction of light in your future courses. In this problem you will apply the methods you have learned to compute a 2D Fourier Transform in MatLab to visualize the diffraction pattern from two common apertures that are used in many optical experiments. Consider the two aperture functions f ( x,y ) = rect x d x rect y d y and f ( x,y ) = cyl " p x 2 + y 2 d r # = cyl r d r where rect x d x = 1 : | x | < | d x | 2 1 2 : | x | = | d x | 2 0 : otherwise cyl r d r...
